30CRMOV9 / 1.7707 alloy ígwè

30CrMoV9 bụ a ígwè nke n'ozuzu e bu n'obi na-emepụta nke quenched na iwe akụkụ, nke na-n'ozuzu machined na emesia nitrided. A na-emepụta alloy 30CrMoV9 site na EAF / VD / LF na-esote electroslag refining (ESR) ma ọ bụrụ na ọ dị mkpa maka ebumnuche pụrụ iche. Ogwe na, ebe ọdabara, a na-edobe forgings na nyocha ultrasonic dabere na ọkwa dị iche iche dịka ihe ndị na-azụ ahịa chọrọ. A na-ebutekarị mmanya na-egbuke egbuke n'ọnọdụ annealed, ma ọ bụ na-egbuke egbuke karịsịa.
